-
FIG. 1 is a disassembled structure diagram of a rotating mechanism according to a first embodiment of the invention, andFIG. 2 is another disassembled structure diagram of a rotating mechanism according to the first embodiment of the invention. - As shown in
FIG. 1 andFIG. 2 , the rotating mechanism includes: abase assembly 10, arotator assembly 11, and a rivetinggasket 12. Thebase assembly 10 is riveted to the rivetinggasket 12, and therotator assembly 11 is sheathed to thebase assembly 10. The rivetinggasket 12 restricts therotator assembly 11 onto thebase assembly 10, and therotator assembly 11 rotates against thebase assembly 10 around an axial direction. As shown inFIG. 1 , after therotator assembly 11 is sheathed to thebase assembly 10, the rivetinggasket 12 is riveted to thebase assembly 10. In this way, therotator assembly 11 is restricted between the rivetinggasket 12 and thebase assembly 10 so that therotator assembly 11 does not leave thebase assembly 10 when therotator assembly 11 rotates against thebase assembly 10. - The
base assembly 10, therotator assembly 11, and the rivetinggasket 12 take on the shape of a circular plate or a cylinder, namely, their cross sections are circular. Nevertheless, they may take on other shapes, for example, cylinder or plate whose cross section is a regular polygon, or cylinder or plate whose cross section is an irregular polygon, or cylinder or plate whose cross section is an ellipse. - Further, the
base assembly 10 includes abase 13 and asleeve 14. Thesleeve 14 can be riveted to thebase 13, or integrated into thebase 13. Thesleeve 14 and thebase 13 may be hollow, the hollow part of thesleeve 14 is connected to the hollow part of thebase 13 to form a central hole, and the circuit connection cable can get through the central hole. Therotator assembly 11 may also be hollow, and thesleeve 14 gets through the hollow part of therotator assembly 11 to let therotator assembly 11 be sheathed to thesleeve 14. - In this embodiment, the
rotator assembly 11 includes at least oneelastomer 17, a concave-convex structure on thebase assembly 10 engages with a concave-convex structure on theelastomer 17 to fix therotator assembly 11 and thebase assembly 10. Specifically, at least one concave hole is set in thebase assembly 10, and at least one convex point is set on theelastomer 17 accordingly. Alternatively, at least one convex point is set on thebase assembly 10, and at least one concave hole is set in theelastomer 17 accordingly; or at least one convex point and at least one concave hole are set on thebase assembly 10, and at least one concave hole and at least one convex point are set on theelastomer 17 accordingly. - Specifically, the
rotator assembly 11 may further include asupport 15 and arotator 16. Thesupport 15 and therotator 16 are sheathed to thesleeve 14.FIG 2 shows how thesupport 15 is sheathed to thesleeve 14. Theelastomer 17 is fixed onto thesupport 15. - At least one roller is set between the
support 15 and therotator 16, and the roller may be aball 18. As shown inFIG. 1 , thesupport 15 may be a plate structure, theball 18 is located in the plate structure, and theball 18 contacts the base 13 so that the rotator assembly rotates against the base assembly more flexibly. - In this embodiment, the concave-convex structure on the
sleeve 14 fits in with the concave-convex structure on theelastomer 17, as described below: - A
concave slot 19 is set around the outer circumference of thesleeve 14, and at least one concave hole (not illustrated in the figure) is set in theconcave slot 19. The at least one concave hole may be distributed evenly on a circle of the concave slot. Accordingly, at least one convex point (not illustrated in the figure) is set on the at least oneelastomer 17 on thesupport 15, where the at least one convex point engages with the concave hole in theconcave slot 19. The number of convex points is the same as the number of concave holes, and the convex points are also distributed on a circle evenly. As shown inFIG. 2 , after thesupport 15 is sheathed to thesleeve 14, the position of the convex point on theelastomer 17 corresponds to the position of theconcave slot 19 exactly. Therefore, in the rotation process, the concave hole in theconcave slot 19 engages with the convex point on theelastomer 17 to generate the angle of rotation level and the sense of handling. For example, if the number of concave holes is 4, which is equal to the number of convex points, the action of rotating for every 90° reaches a new level of rotation. Theelastomer 17 is elastic to some extent. When the concave holes engage with the convex points, theelastomer 17 presses the convex points on the elastomer into the concave holes. In this way, thesleeve 14 is fixed onto thesupport 15 relatively, and the rotator assembly is fixed onto the base assembly. When inverse torque is applied to the rotator assembly and the base assembly, theelastomer 17 may generate elastic deformation, and the convex points can come out of the concave holes under a proper torque force so that the rotator assembly rotates against the base assembly. Because the rotation level of the rotation mechanism can be set flexibly as required, the rotation may stop every time when the rotation reaches a specific angle, which increases the flexibility and convenience of using the device. - The foregoing concave-convex structure is only an example of this invention. Alternatively, at least one convex point is set on the
concave slot 19, and at least one concave hole that engages with the convex point is set in the at least oneelastomer 17; or at least one convex point and at least one concave hole are set on theconcave slot 19, and at least one concave hole that engages with the convex point and at least one convex point that engages with the concave hole are set on the at least oneelastomer 17. - In this embodiment, at least one
machine hole 20 is set in thebase 13, and at least onemachine hole 21 is set in therotator 16. The machine holes are designed to fix the rotating mechanism onto the corresponding electronic device or component. The machine holes may be through-holes or blind holes set in thebase 13 and therotator 16. - The assembly process of the rotating mechanism shown in
FIG. 1 is: Rivet thesleeve 14 to the base 13 to form thebase assembly 10; fasten the at least oneelastomer 17 to the corresponding position of thesupport 15, sheathe thesupport 15 to thesleeve 14, and let the convex points of theelastomer 17 of thesupport 15 be embedded into theconcave slot 19 of thesleeve 14 exactly; load the at least oneball 18 onto thesupport 15, and sheathe therotator 16 to thesleeve 14; install theriveting gasket 12, and rivet theriveting gasket 12, therotator 16, thesupport 15, and thebase assembly 10 together. Besides, when therotator assembly 11 rotates against thebase assembly 10, therotator 16 keeps fixed to thesupport 15 relatively. For example, therotator 16 may be fastened to thesupport 15 through weld, rivet, or bolts. Alternatively, a fixing slot (not illustrated in the figure) may be set on therotator 16. The fixing slot corresponds to theedge 151 of thesupport 15, and theedge 151 of thesupport 15 is embedded into the fixing slot of therotator 16 so that therotator 16 is fastened to thesupport 15. -
FIG. 3a is a structure diagram of an assembled rotating mechanism according to the first embodiment of the invention, andFIG. 3b is a sectional structure diagram of an assembled rotating mechanism according to the first embodiment of the invention. Specifically,FIG. 3b is an axial sectional diagram of the rotating mechanism shown inFIG. 3a . As shown inFIG. 3a andFIG. 3b , thesupport 15 may be a plate structure, a through-hole may be set in thesupport 15, theball 18 is located in the through-hole, and theball 18 contacts both thebase 13 and therotator 16. In this way, when the rotator assembly rotates against the base assembly, theball 18 props up between the base 13 and therotator 16, and the rotation of the rotator assembly against the base assembly is more flexible. The diameter of theball 18 may be 0.5-0.8 mm, and the total axial thickness of the rotating mechanism is 2 mm or smaller, and the outer diameter of the rotating mechanism is 10 mm or smaller, and therefore, the rotating mechanism fits in well with an ultra-thin electronic device. The rotating mechanism shown inFIG. 3a has acentral hole 30, and a cable may get through the central hole. For example, the USB connection cable may get through thecentral hole 30 of the rotating mechanism to get connected to a Printed Circuit Board (PCB) at the bottom. It should be noted that the holes in thesupport 15 may have a blind hole or recess. In this case, theball 18 is set in the blind hole or recess, theball 18 reaches and contacts thesupport 15 and thebase 13. Therefore, when the rotator assembly rotates against the base assembly, theroller 18 props up between the base 13 and thesupport 15. Nevertheless, theball 18 is only an embodiment of the roller. In practice, any variation of the roller is appropriate so long as the roll of the roller relieves relative resistance between the rotator assembly and the base assembly and improves flexibility of relative rotation between the rotator assembly and the base assembly. For example, the roller may be a rolling rod. The rolling rod may be embedded into thesupport 15 orrotator 16 through an axle or by other means, and the rolling rod contacts thebase 13. Therefore, when the rotator assembly rotates against the base assembly, the rolling rod props up between the base 13 and thesupport 15 orrotator 16. -
FIG. 4a is a disassembled structure diagram of a rotating mechanism according to a second embodiment of the invention. As shown inFIG. 4a , the rotating mechanism includes: abase assembly 40, arotator assembly 41, and ariveting gasket 42. Thebase assembly 40 is riveted to theriveting gasket 42, and therotator assembly 41 is sheathed to thebase assembly 40. Theriveting gasket 42 restricts therotator assembly 41 onto thebase assembly 10, and therotator assembly 41 rotates against thebase assembly 40 around an axial direction. As shown inFIG. 4a , after therotator assembly 41 is sheathed to thebase assembly 40, theriveting gasket 42 is riveted to thebase assembly 40. In this way, therotator assembly 41 is restricted between theriveting gasket 42 and thebase assembly 40, and therotator assembly 41 does not leave thebase assembly 40 when therotator assembly 41 rotates against thebase assembly 40. - The
base assembly 40, therotator assembly 41, and theriveting gasket 42 take on the shape of a circular plate or a cylinder, namely, their cross sections are circular. Nevertheless, they may take on other shapes, for example, cylinder or plate whose cross section is a regular polygon, or cylinder or plate whose cross section is an irregular polygon, or cylinder or plate whose cross section is an ellipse. - Further, the
base assembly 40 includes abase 43 and asleeve 44. Thesleeve 44 may be riveted to thebase 43, or integrated into thebase 43. Thesleeve 44 and the base 43 may be hollow, the hollow part of thesleeve 44 is connected to the hollow part of the base 43to form a central hole, and the circuit connection cable can get through the central hole. Therotator assembly 41 is sheathed to thesleeve 44. That is, therotator assembly 41 is hollow, and thesleeve 44 gets through the hollow part of therotator assembly 41. - In this embodiment, the
rotator assembly 41 includes anelastomer 47, a concave-convex structure on thebase assembly 40 engages with a concave-convex structure on theelastomer 47 to fix therotator assembly 41 and thebase assembly 40. Specifically, at least one concave hole is set in thebase assembly 40, and at least one convex point is set on theelastomer 47 accordingly. Alternatively, at least one convex point is set on thebase assembly 40, and at least one concave hole is set in theelastomer 47 accordingly; or at least one convex point and at least one concave hole are set on thebase assembly 40, and at least one concave hole and at least one convex point are set on theelastomer 47 accordingly. - Specifically, the
rotator assembly 41 may further include arotator 46. As shown inFIG. 4a , theelastomer 47 and therotator 46 are sheathed to thesleeve 44. One plane of theelastomer 47 contacts thebase 43, and the other plane of theelastomer 47 contacts therotator 46. In this way, theelastomer 47 can reach and contact both therotator 46 and thebase 43. -
FIG. 4b is a structure diagram of an elastomer in the rotating mechanism according to the second embodiment of the invention. As shown inFIG. 4b , theelastomer 47 is a component composed of onesupport part 471 and multipleelastic parts 472. The angle between theelastic part 472 and the plane of thesupport part 471 is an obtuse angle, and theelastic parts 472 are designed to keep an axial distance between thesupport 471 and therotator 46. Theelastic part 472 may be an elastic metal plate. While in service, more than twoelastic parts 472 are set on thesupport part 471. One plane of thesupport part 471 contacts thebase 43, and a concave-convex structure is set on the contact plane of thesupport part 471 which contacts thebase 43. Theelastic part 472 contacts therotator 46. Because theelastic part 472 makes theelastomer 47 elastic, the axial distance between theelastomer 47 and therotator 46 varies with the elasticity of theelastomer 47. - In this embodiment, the concave-convex structure on the base 43 fits in with the concave-convex structure on the
elastomer 47, as described below: - At least one
convex point 48 is set on the plane of theelastomer 47 against the base 43 (namely, the contact plane of thesupport part 471 of theelastomer 47 which contacts the base 43), and at least oneconcave hole 49 that engages with theconcave point 48 is set in the plane of the base 43 against theelastomer 47. Specifically, the number ofconvex points 48 is the same as the number ofconcave holes 49, and the convex points and theconcave holes 49 may be distributed on a circle evenly. A through-hole 473 exists in the middle of thesupport part 471 of theelastomer 47. Theelastomer 47 is sheathed to thesleeve 44 through the through-hole 473. Afterward, in the rotation process, theconcave hole 49 engages with theconvex point 48 to generate the angle of the rotation level and the sense of handling. For example, if the number ofconcave holes 49 is 4, which is equal to the number ofconvex points 48, the action of rotating for every 90° reaches a new level of rotation. Theelastomer 47 is elastic to some extent. When theconcave holes 49 engage with theconvex points 48, a proper force may be applied to rotate theconvex points 48 out of the concave holes 49. Specifically, when theconcave holes 49 engages with theconvex points 48, theelastic part 472 of theelastomer 47 reaches and contacts therotator 46, and theelastomer 47 presses the convex points on thesupport part 471 into the concave holes of thebase 43. In this way, thesleeve 44 is fixed onto theelastomer 47 relatively, and the rotator assembly is fixed onto the base assembly. When inverse torque is applied to the rotator assembly and the base assembly, theelastomer 47 may generate elastic deformation, and theconvex points 48 can come out of theconcave holes 49 under a proper torque force so that the rotator assembly rotates against the base assembly. - The foregoing concave-convex structure is only an example of this invention. Alternatively, at least one convex point is set on the
base 43, and at least one concave hole that engages with the convex point is set in theelastomer 47; or at least one convex point and at least one concave hole are set on thebase 43, and at least one concave hole that engages with the convex point and at least one convex point that engages with the concave hole are set on theelastomer 47. Besides, thesupport part 471 may be a circular rod or plate shown inFIG. 4a andFIG. 4b ; or, thesupport part 471 may take on other shapes, for example, cylinder or plate whose cross section is a regular polygon, or cylinder or plate whose cross section is an irregular polygon, or cylinder or plate whose cross section is an ellipse. All such shapes are appropriate so long as a through-hole 473 is set in the middle of the rod or plate of such shapes. - In this embodiment, at least one
machine hole 50 is set in thebase 43, and at least onemachine hole 51 is set in therotator 46. The machine holes are designed to fix the rotating mechanism onto the corresponding electronic device or component. The machine holes may be through-holes or blind holes set in thebase 43 and therotator 46. - The assembly process of the rotating mechanism shown in
FIG. 4a is: Rivet thesleeve 44 to the base 43 to form abase assembly 40; sheathe theelastomer 47 to thesleeve 44, and theelastomer 47 contacts thebase 43; sheathe therotator 46 to thesleeve 44; install theriveting gasket 42, and rivet theriveting gasket 42,rotator 46,elastomer 47, andbase assembly 40 together. Besides, when therotator assembly 41 rotates against thebase assembly 40, therotator 46 keeps fixed to theelastomer 47 relatively. For example, therotator 46 may be fastened to theelastomer 47 through weld, rivet, or bolts. Alternatively, a fixing slot (not illustrated in the figure) may be set on therotator 46. The fixing slot corresponds to theelastic part 472 of theelastomer 47, and theelastic part 472 of theelastomer 47 is embedded into the fixing slot of therotator 46 so that therotator 46 is fastened to theelastomer 47. - The
rotator 46 may also be relatively fixed to theelastomer 47 by other means. SeeFIG. 7a to FIG. 7d .FIG. 7a is a disassembled structure diagram of another rotating mechanism according to the second embodiment of the invention;FIG. 7b is a main topology of a sleeve in another rotating mechanism according to the second embodiment of the invention;FIG. 7c is a left view of a sleeve in another rotating mechanism according to the second embodiment of the invention; andFIG. 7d is a top view of a sleeve in another rotating mechanism according to the second embodiment of the invention. Thesleeve 44 may not be fixed to thebase 43, and thesleeve 44 includes a restrictingpart 441, acylindrical part 442, and ariveting part 443. Thecylindrical part 442 gets through the circular through-hole in the middle of thebase 43; theelastomer 47 and therotator 46 are sheathed to thecylindrical part 442, and theriveting gasket 42 is riveted to theriveting part 443. Because an area of the restrictingpart 441 is greater than an area of the circular through-hole of the base 43 (the restrictingpart 441 is located on a side of thesleeve 44 that contacts thebase 43. The area enclosed by the edge of the restrictingpart 441 is greater than the area of the circular through-hole in the middle of the base 43). Therefore, the restrictingpart 441 and theriveting part 443 restrict thebase 43,elastomer 47, androtator 46 together. A cuttingplane 444 is set on thesleeve 44. That is, one or more columns whose bottom is a bow shape are cut along the axis of thecylindrical part 442, and therefore, the cross section of thecylindrical part 442 is an incomplete circle. Theelastomer 47 and the through-hole in the middle of therotator 46 are set according to the cross section of thecylindrical part 442, and therefore, theelastomer 47 and the through-hole in the middle of therotator 46 also form an incomplete circle. In this way, theelastomer 47, therotator 46, and thecylindrical part 442 are clasped to each other; when therotator assembly 41 rotates against thebase assembly 40, therotator 46 keeps fixed to theelastomer 47 relatively, and the base 43 can rotate around thesleeve 44. - The total axial thickness of the rotating mechanism in this embodiment is 2 mm or smaller, and the outer diameter of the rotating mechanism is 10 mm or smaller, and therefore, the rotating mechanism fits in well with an ultra-thin electronic device. The rotating mechanism has a central hole, and a cable may get through the central hole. For example, a USB connection cable may get through the central hole of the rotating mechanism to get connected to a Printed Circuit Board (PCB) at the bottom. Because the rotation level of the rotation mechanism can be set flexibly as required, the rotation may stop every time when the rotation reaches a specific angle, which increases the flexibility and convenience.
